Description

I L5 2 separation device in a feed line for Pneumatically conveying
textile fibres The invention relates to a device in a feed line for pneumatically conveying textile fibres, especially in spinning preparation.
In a known device, there are two closure flaps, the first closure flap serving to close off the feed channel and being able to close or uncover the first connecting opening, and the second closure flap being able to close or uncover the second connecting opening. The second closure flap is spring-biased into the closed position so that it opens the second connecting opening owing to the pressure building up in front of the closing-off closure flap when the latter pivots. The use of two closure flaps is complicated in terms of construction and mounting. A further problem is that, if the spring bias or the pivot bearing is impaired, the second closure flap may remain partially or completely closed during operation, thus preventing separation of the fibre material and causing an undesirable pressure burden.
It is an object of the invention to provide a closure device that avoids the disadvantages mentioned and, in particular, is simple in construction and reliable in operation.
The present invention provides a device in a feed line for pneumatically conveying textile fibres, compris ing a closure flap arranged downstream of and activated by a detector that responds to sparks and/or metal particles conveyed with the fibres, which closure flap, is so movable that it can close off the feed line and at the same time uncover a first connecting opening, present in the feed line, into a separation vessel when the detector responds, the device comprising a second connecting opening into the separation vessel, which second connecting opening is normally kept closed, wherein the one closure flap normally keeps the second connecting opening closed and unblocks the second connecting opening when the detector responds.
According to the invention, there is only one closure flap, which closes off one route (closing-off of the feed line) and at the same time opens up two routes (first and second connecting openings between feed line and separation vessel). In the non- closing-off position, the one closure flap closes both the first and the second connecting openings. In contrast to the known device, the use of one closure flap is simple with regard to construction and with regard to mounting. In addition, the second connecting opening is inevitably and reliably opened by the one closure flap present.
Preferably, the closure flap is movable by means of a pivoting movement. Advantageously, there is a single closure flap. Preferably, the pivot axis is assigned to the middle of the closure flap. Preferably, the closure flap has two pivoted wings. The closure flap is advantageously in one piece. Advantageously, on the inner wall of the feed line there is a stop which is in contact with an edge region of one pivoted wing of the closure flap during the closing-off operation. Prefer- ably, there is provided opposite the stop an abutment against which the other pivoted wing rests at least partially during the closing-off operation. The closure flap is preferably coupled to a drive, for example a pneumatic cylinder. Advantageously, the pivot axis of the closure flap is arranged to face away from the direction of flow. In a device in which the separation vessel is divided into two parts by a collecting screen, the collecting screen is preferably so fine that fire and sparks are not able to penetrate it. Preferably, the collecting screen has a fineness of approximately from 0.1 to 0.3 mm. Advantageously, the collecting screen consists of high quality alloy steel.
Advantageously, the collecting screen is fastened to a perforated plate. Preferably, the first connecting opening is covered by a screen, for example, wire mesh. Preferably, a transport car is arranged beneath the separation vessel. Advantageously, the separation vessel has on its underside a pivoted flap or the like that can be closed tightly. In the case of a device in which there are two successive fibre stations processing loose fibres, the device is advantageously provided in a spinning preparation system. Preferably, the device is assigned to the feed line between the bale opener and the subsequent fibre station. Preferably, the closure flap can be pivoted into the closing-off position counter to the direction of flow in the transport line.
The present invention further provides a separating device for separating material from a stream of fibre flocks, the device comprising a fibre conveying line, a separation vessel arranged adjacent to the fibre conveying line, and first and second connecting openings connecting the separation vessel with the fibre conveying line, the device comprising a closure means, and the closure means being movable from a position in which it closes the first and second openings to a position in which it blocks the fibre conveying line between the first and second connecting openings whilst leaving the first and second connecting openings unblocked.
In addition, the invention provides a method of separating contaminated fibre material from a pneumatically conveyed stream of fibre flocks in a feed line comprising closing off a normal fibre path and diverting the contaminated fibre material from said normal path through an opening into a separation vessel, separating the contaminated material from the air carrying it, and passing at least a proportion of the air through another opening back into the feed line.
Figure 4 Certain embodiments of the invention will now be described with reference to the accompanying schematic drawings, of which:
Figure 1 is a side view of a separating device embodying the invention arranged downstream of a bale opener; shows the device of Figure 1 with two positions of the closure flap; are a side view and a plan view, respectively, of the collecting screen; and shows part of a feed channel in which a closure flap is installed.
Figure 1 shows the device according to the invention downstream of a bale opener 1, for example, of the type made by Triltzschler GmbH & Co. KG and known as a BLENDOMAT BDT. A movable take- off unit la with rapidly rotating toothed rollers 1b, lc removes fibre flocks from the stationary fibre bales, during which operation pieces of metal may also be removed which may lead to malfunctions in the machines downstream. When the pieces of metal come into contact with the rapidly rotating toothed rollers lb, lc sparks may be formed which may set fire to the fibre material. The fibre flocks are fed pneumatically into a horizontal suction channel 3 and, from there, via fibre transport lines 4 and 5, into a fibre Figure 2 Figures 3a, 3b processing machine 6 arranged downstream. Between the suction channel 3 and the transport line 4 (vertical ascending line) there is a bend 7 and, between the transport line 4 and the horizontal transport line 5, 5 there is a bend 8.
In the transport line 5 there are a first connecting opening 9 and, upstream of said first connecting opening 9, a second connecting opening 10 (see Figure 4), beneath which there is a separation vessel 11 for flocks deleter- iously affected by sparks or pieces of metal. In the region of the connecting openings 9, 10 there is a pivoted closure flap 12, the pivoted wings 12a, 12b of which keep the connecting openings 9, 10 closed in the position shown in Figure 1. The pivot axis 12c, for example a pivot bearing, in the middle of the one-piece closure flap 12 is arranged at a distance a (see Figure 2) below the inner wall surface 5a, so that the front face 12d is approximately flush with the inner wall surface 5a.
The separation vessel 11 is divided into two parts by a collecting screen 13, the connecting opening 10 being in communication with the interior of the vessel 11 on one side of the screen 13 and the connecting opening 9 being in communication with the interior on the other side of the screen 13. A transport car 14 is arranged beneath the separation vessel 11. The separation vessel 11 has on its underside a pivoted flap 15 which can be closed tightly and which is able to close off or uncover an opening through which the contaminated fibres fall into the transport car 14.
Viewed in the direction of movement (arrow A) of the fibre flocks in the transport line, there is arranged upstream of the closure flap 12, at the end of the channel 3, a detector 16 that responds to sparks, for example an infrared sensor. The closure flap 12 or the actuator 17, for example a pneumatic cylinder, are operationally connected to a control device 18 in such a manner that the closure flap 12 can be pivoted as a consequence of the passage of sparks through the region of the detector 16 (see Figure 2). Between the closure flap 12 and the detector 16 there are two curved bends 7 and 8 each with a change in direction of 90, with the result that the length of transport line is adequate, given the reaction time between spark detection and pivoting of the closure flap 12 and, owing to the arrangement of the line, incorporating an ascending line 4, there is a considerable saving in space.
As shown in Figure 2, on the inner wall surface 5b there is a stop 19 which is in contact with the edge region of the face 12d of the pivoted wing 12a of the closure flap 12 during the closing-off operation.
Opposite the stop 19, in the region below the pivot axis 12c, there is an abutment 20 against which the face 12e of the other pivoted wing 12b rests at least partially during the closing-off operation. The second connecting opening 9 (see Figure 4) is covered by a wire mesh 21 8 - which is arranged to face the rear side 12e of the pivoted wing 12all and beneath the pivot axis 12c. The end of the pivoted wing 12b11 is arranged at a distance b below the inner wall surface 5a, so that arriving fibre material is able to slide off in the direction of flow A as if over roof shingles.
In Figure 2, the closure flap 12 is shown by broken lines in the position in which it is when there are no airborne sparks, the pivoted wing 12all keeping the first connecting opening 9 closed and the pivoted wing 12b11 keeping the second connecting opening 10 closed. As soon as the detector 16 signals the flight of sparks, the closure flap 12 is pivoted by a suitably positioned pneumatic cylinder 17 by approximately 900 into the position shown by continuous lines, the pivoted wing 12a simultaneously closing off the feed channel 5 and, in addition, the pivoted wing 12a uncovering the first connecting opening 9 and the pivoted wing 12b uncovering the second connecting opening 10. By pivoting the one closure flap 12 in the direction of the arrow D one route (feed channel 5) is closed and two routes (first and second connecting openings 9 and 10) are simultaneously opened. The pivoted wing 12a is pivoted in the direction of the arrow D counter to the direction of flow A from the non- closing-off position 12all into the closing-off position 12al. The closure flap 12 is returned to the non-closing-off position in the direction of the arrow E.
The collecting screen 13 extends from the lower end of the abutment 20 to the wall surface 11a at an angle, so that the interior of the separation vessel 11 widens downwardly below the second connecting opening 10.
As shown in Figure 3, the collecting screen 13 consists of a wire mesh 22 which on one face is fitted to a perforated plate 23. Viewed in the direction C in the which the air passes through, the supporting perforated plate 2 1 3 is arranged on the side towards the first connecting opening 9 and the wire mesh 22 is arranged on the side towards the second connecting opening 10 (cf.
arrangement as shown in Figure 2). The perforated plate 23 has square through-openings 23a (see Figure 3b) with a side length c of 20 mn and webs 23b having a width d of 4 mm. The openings may also be circular. The wire mesh 22 has a mesh size (inside width between two adjacent wires) of approximately 0.2 mm and a wire diameter of approximately 0.15 mm. Figure 3b is a view onto the collecting screen 13 in the direction of the arrow F in Figure 3a. 20 Figure 4 shows a closure flap 12 in the closingoff position, that is to say, the feed channel 5 is closed. At the same time, the first connecting opening 9 and the second connecting opening 10 are open. Between the collecting screen 13 and the pivot bearing 12c there is a seal 24. In use, when sparks or pieces of metal are detected by the detector 16, the control device causes a drive means, for example, a pneumatic cylinder, to rotate the - 10 closure flap 12 from the non-closing off position to the closing-off position (that is, with reference to Figure 2, from the position indicated by the broken lines to the position indicated by the continuous lines). Fibre material then passes through the opening 10 into the separation vessel 11, air passing through the screen 13 and the opening 9 back into the line 5. The fibre material collected in the separation vessel 11 may be discarded through the opening at the bottom thereof by opening the flap 15, whereby the material can be deposited into the transport car 14.
